canon rumors FORUM

PhotoRumors guy is reporting the next Sony a99 will have 102 autofocus points. This got me thinking – are we getting into overkill here?

Granted, it's not even been released yet, so there is no way to know just how good or bad the autofocus will be. But, I have to wonder if we are getting to the point of diminishing returns here. Are 102 autofocus points better than 61 points?

Is this the next form of megapixel wars? "Your 1DX has a mere 61 autofocus points while we have 102."

Realistically, how many autofocus points can be crammed into the space and do they, at some point, begin to make the focusing worse, not better.

Just something I'd like to hear opinions on from those who understand this sort of thing more than I do.

This will be very interesting to see - the first essentially mirrorless [EVF, not OVF] FF prosumer camera. Bold move on Sony's part. I hope they do it right, that the viewfinder is well reviewed. They just need to figure out the AF and get rid of the translucent mirror altogether. I can't help but wonder if that doesn't hurt IQ.

"Sony's not unleashed a full frame camera for some time." Looks like they're unleashing one soon -- now we'll know who let the dogs out!

The "purported spec sheet breaks cover" and they elbow their way to the front to see it. The battle of the pudgy nerds ensues! Also, there are "other nuggets of interest." And I don't think they're talking about McDonalds (But maybe they are -- all warriors need nourishment at some point. That elbow flinging can be quite a workout.)

The drama only subsides when "the rumor-mill" kicks in to provide a trite ending to an otherwise thrill-packed adventure in Futureland.

Yes, and mostly because of how Sony did it. Only 11 of those AF points are cross-point, so, by that measure, its really on par with the 60D/T4i AF for cross-points. So, chances are the 102 is more just for the number than for practicality. But, if we start getting AF systems even more complex than the 5dIII/1DX, they could genuinely be 100+ pt AF with 90 cross-points and be better.

Roger at Lensrental had a cool break-down of why the new Canon AF is so good with the newest lenses. The lessons from the end seem to indicate that you could go further. But, in reality, it's gonna take decades to revamp all the lenses and all the camera AF systems.

I don't get why everyone is being so negative about this rumour. If it's true then Sony are making a strong return to the full frame fold; should they see fit to release some new Zeiss AF glass to go with it, then they will be a serious choice for prosumers and professionals. This can only be a good thing for all of us, the Canikon duopoly of the high end is doing nothing but inflating prices.

I totally agree. I'd be even more happy if they could release some good quality telephoto with half the price of Canikons.

or they can do what Nikon does and make then translucent so they don't get in the way. It is only a matter of time before the entire viewfinder is covered. Canon's lead with the 61pt was never meant to last long. 100-200 AF sensors are going to be the norm from all OEMs in the next gen bodies.
